v CUNVERTIBLE HAND AX.

Specification of Letters Patent.

rammed June is, 1922.

Application: filed October 25, 1820. Serial No. 419,334.

To all whom it may concern:

Be it known; that I, BARN-BY. G'IDMARK, a citizen of the United States, residing. at Gloquet, in the county of Carlton and State of Minnesota, have invented certain new and useful Improvements in Convertible Hand Axes, of which the following is a specification, reference being had thereinuto the" accompanying drawing.

This invention relates to adjustable convertible hatchets and has special reference to I commonly used in connection with a hatchet whereby a modified form of hatchet may be provided.

In the accompanying drawings forming part of this application and in which like reference characters indicate like parts:

Figure 1 is a perspective view of the head of a hatchet applied to a handle with the simpler form of my improved fastening means;

Figure 2 is a side elevation of the outer extremity of the fastening attachment;

Figure 3 is a top plan view of the upper edge of the fastening means showing its relative position to the handle;

Figure 4 is a side elevation of Figure 8;

Figure 5 is a sectional view on the line 5, Figure 6;

Figure 6 is a side elevation of the device when used as an adz; and

Figure 7 is a vertical sectional view on the line 7-7, Figure 6. i

1 represents the head of the hatchet and 2 the handle upon which the head is commonly mounted. In the installation of my improved holding means or fastener, the end of the handle 2 is shaped in substantially the ordinary manner to be driven within the head of the hatchet, except that it is reduced somewhat more than is common in order to be freely inserted within the head and it is provided with grooves upon the upper and lower edges thereof and upon the opposite sides,

said. grooves being for the reception of the strapsB and l of the skeleton ferrule, the inner end of which comprises the ring 5 formed integral with the straps 3 and a, said straps supporting intermediate their outer ends the end piece 6. The grooves upon the opposite sides of the shaped handle are for the reception of the spring straps 7 and 8 which are securely riveted tothe underside of the ring 5, as at 9:; their free ends being normally spaced apart a greater distance than the transverse width of the socket: within the liead'l, as clearly shown in Figure 8 ofthe drawings. The extreme ends 10 of these straps are bent outwardly and are for the purposeof overlapping the outer edges of the socket in the tool head when thelatter is inplace uponthe handle, as seen in-Figure 1.

A thumb button 11 is pivotally mounted centrally upon the exteriorof the end piece 6 of the skeleton ferrule, and under the head of the pivotal support 12 for such. button, upon the opposite side of the end piece 6 to that of the button, is a spring 13 which normally tends to keep the button tightly engaging the face of the end piece and said button has formed on the inner face thereof oppositely disposed V-shaped projections 14 for registering within similarly shaped recesses in the face of the end piece when the button is positioned transversely thereof, as shown in Figures 1 and 2, thus the locked position of the button 11 is at all times insured after once having been properly established. The skeleton ferrule is held in position on the end of the previously prepared handle 2 by a suitable through rivetindicated at 15.

By this means of attachment it is evident that the hatchet head 1 may be quickly removed by the turning of the button 11 to a vertical position and pinching in of the bent ends 10'1O of the straps 7 and 8 which will permit of the ax head being readily slipped off from the handle over the bent ends of the resilient members 7 and 8. The hatchet may be applied to the handle with the bevel of its cutting edge in either direction as desired, by applying the handle to the head upon the opposite side thereof.

ln Figures 5, 6 and 7, I have illustrated a solid removable ferrule 17 as'cooperatively associated with the skeleton ferrule previously described and by which the former is held in position upon any form of handle previously prepared for same and particularly suitable for the employment of the hatchet head as an adz.

Upon one side of the ferrule 17 is securely fixed an extension 18 which is bent at right angles away from its body portion as at 19 and then again at right angles forwardly as at 20 forming a bracket for the hatchet head support 21, while upon the opposite side of the ferrule 17 is slidably held the adjustable bracket 22, which is, in all respects, similar to the bracket 18, except that it carries upon its outerend a thumbscrew 23 adjustably applied to the opposite end of the hatchet head support, so that the latter may be removed or applied at will. The slidable member 22 is dovetailedintothe side of the ferrule 17 as clearly shown in Figure 7, and a centrally disposed thumbscrew 24: is provided for holding the bracket in position when properly extended for supporting the hatchet head and the entire hatchet head support may be quickly removed or adjustedby the manipulation of the skeleton ferrule before described.

From the foregoing it is evident that one having a hatchet equipped with this form of holding means may quickly remove the head of the hatchet from the hatchet handle and by applying the adz holder to the handle and have a tool which may be used in the form of an adz, especially convenient and useful in the art of carpentry.

Having thus described my invention, what 1 claim and desire to secure by Letters Patent, is:

l. A fastening means for hatchets of the class described comprising an inner ferrule, an outer ferrule surrounding the inner ferrule, means carried by the former for securely holding the outer ferrule thereto, brackets extending forwardly of the outer ferrule and carried thereby and a hatchet head holder carried by the brackets, substantially asdescribed. y

2. A fastening means for hatchets of the class described including a skeleton ferrule, two opposite resilient holding members fixed longitudinally of the ferrule having their opposed ends bent outwardly, and means pivotally carried upon theiend of the ferrule for fastening or releasing said holding members, substantially as and for the purpose described. i

i In testimony whereof I hereunto affix my signature in the presence of two witnesses.

BARNEY GIDMARK.
